damage and allow unfiltered air to
enter the engine if it is not properly
seated.
8. Install the air filter housing cover.
9. Engage the clips to secure the air filter housing cover to the air filter housing.
10. Reconnect the two boots on the air filter housing cover and torque to

CHANGING THE ENGINE AIR
FILTER - 3.3L WARNING:
To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
Note: When servicing the air cleaner, do
not allow foreign material to enter the air
induction system. The engine is susceptible
to damage from even small particles.
When changing the air filter element, use
only the air filter element listed.
Change the air filter element at the proper
intervals. See
Scheduled Maintenance
(page 482). 1.
Release the clamps that secure the air
filter cover to the housing.

ENGINE COOLANT CHECK WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 482).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir. Note:
Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow
this instruction could result in personal
injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)
